GEOG 310 Lecture Notes - Lecture 10: Water Scarcity, Ecological Footprint, Integrated Urban Water Management
Document Summary
Today"s lecture: water scarcity, dispelling myths about water in canada, potential solutions to water dilemmas in canada. Global water scarcity: currently about 1/3 of the global population lives in with water scarcity, by 2025, this is expected to rise to nearly 2/3. Canada: 20% of lake water, but in terms of world"s renewable freshwater, canada only has 6, but per capita, canada leads the world in terms of water resources. So, is canada water scarce: no, when you consider total annual renewable fresh water supply per capita, but we need to consider: Geographical mismatch" between population(where, how many, consumption rate) and water sources(where, how much, what quality) Physical and social scarcity: in canada, a lot of rivers are actually inaccessible. So we have a lot of water, but not in the right place. Lowering the carrying capacity and may not sustain the same amount of population. Water footprint: water footprint of a nation(or of a person)
